lol, i highly doubt that 66 was only giving you 66watts..... remember the term "cheater", just like the pre-99 usamps, orions, ande a plethora of others. there was even a soundstream rated at 1/4wattrmsx2, yet would actually crank over 1k, iirc don't remember the exact numbers. yes, you can still get strokers if you keep your eye out, and i even remember seeing parts to rebuild them. by far only decent pre-fab enclosure that didn't start to cap output at higher levels i have seen and run is an obcon godzilla. 146.6 with 2 crossfire bmf-10's....from like '02, 03?.....still got the thing, but one broke the cone in half, so i'm going to eventually stuff my perfects in there and see what happens.... anywhoo, have a box designed for the subs, and keep reading up on how to fine tune the amp, and make sure it's not just in need of tune..... the subs should be fine for what you want
